Description

KFDO900 Do Meter Stainless Steel Sensor Water Quality For Aquaculture Industrial
Product Introduction

dissolved oxygen measuring instrument is based on fluorescence quenching principle.The fluorescent material at the front of the sensor is a special platinum porphyrin compound with a polyester foil that allows gas molecules to pass through. The surface is coated with a black light-blocking material to avoid interference by sunlight and other fluorescent substances in the water.
When blue light hits the fluorescent material, the fluorescent material is excited and emits red light. Since oxygen molecules can carry away energy (quenching effect), the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules.By measuring the phase difference between the excitation red light and the reference light and comparing with the internal calibration value, the concentration of oxygen molecules can be calculated.After linearization and temperature compensation, the final value is output.


The advantage of fluorescence dissolved oxygen

In general, the fluorescence dissolved oxygen instrument can measure the oxygen content of water without flow rate, which is more accurate without the need for magnetic stirring machine.Although the first purchase cost is high, the electrode is very easy to use. It is usually replaced every 2-3 years, unlike the polarographic method, which requires electrode replacement, and the cost is very expensive.

Performance characteristics:

● Innovative fluorescence principle, no need to replace the diaphragm and electrolyte, basic maintenance free;
● No need to replace the fluorescent cap, lower use cost;
● No oxygen consumption, no flow rate and agitation requirements;
● will not be "toxic" because of sulfide, to overcome environmental interference;
● Free from cross interference of H2S, PH, CO2, NH3, SO4, CL-, CL2, etc.
● Higher resolution and measurement accuracy;
● The service life of the sensor is up to 5 years;

Q&A
What is zero drift?
It refers to the size of the indicating value of the automatic analyzer changing within a certain period of time when the zero correction liquid specified in this technical requirement is used as the sample for continuous testing.

What is Range drift?
refers to the change of the indicating value of the automatic analyzer in a certain period of time when the range correction liquid specified in this technical requirement is used as the sample for continuous testing.

What is Mean fail-free?
continuous running time refers to the ratio of the total running time (h) of the automatic analyzer to the number of failures (times) during the test period, which is shown in "MTBF". The unit is h/time.

What is response time (T90)?
electrodes from range correction fluid to zero correction fluid, the determination of displayed value range correction liquid concentration 90%.
